HAY-CARRIER.

SPECIFICATION forming part of Letters Patent No. 795,001, dated July 18, 1905.

Application filed March 15,1905. Serial No. 250,191.

To (LZZ II/7107771 it may concern:

Be it known that I, PHILIP A. MYERS, a citizen of the United States, residing at Ashland, in the county of Ashland and State of Ohio,

have invented certain new and useful Improvements in I*Iay()arriers,of which the fol-' lowing is a specification, reference being bad therein to the accompanying drawings.

This invention relates to hay-carriers, and [0 more particularly to that type of carrier set forth in two applications heretofore filed by me -to wit, April 7, 1904, Serial No. 202,005, and October 1 1, 1904, Serial No. 228, 125.

The general object of the present invention is to adapt that type of carrier for operation in connection with a knocker located above the track, as is preferable in the case of what is known as a single-rail track, and to provide a construction whereby the carrier may be rendered reversible as to the direction of its travel from the knocker when so located.

To these and other ends my invention consists in certain novel features, which I will now proceed to describe and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is a side elevation of a carrier embodying my invention in one form, the same being shown open or unlocked. Fig. 2 is a view of the same from the opposite side. Fig. 3 is a rear elevation of the same, partly in section. Fig. 1 is a vertical section taken chiefly in a central transverse plane. Fig. 5 is a plan section taken immediately below the body of the car- 55 riage; and Fig. 6 is a detail elevation of the upper part of the structure, illustrating a modification? In the said drawings, in which there is shown a structure embodying my invention in one 4 form, 1 indicates the track, shown as a singlerail track, and 2 the knocker, which is located above said track and is provided with cam inclines 3, oppositely inclined, and with the stop projections 4:, one at each end, in ad Vance of the corresponding inclines 3, which latter are in duplicate on each side of the track. On this track there travels a carriage 5, supported on wheels 6, said carriage in turn supporting the frame of the carrier, which is swiveled to the carriage in any approved manner, that shown being a well-known form in which the carriage is provided with an annular flange or track 7, embraced by a grooved annular flange 8 on the frame of the carrier.

In the present instance I have shown the frame of the carrier as constructed in substantial accordance with my prior application Serial No. 202,005, although it may be constructed in accordance with my prior application Serial No. 228,425. trated the frame is composed of a fixed part or member (designated as a whole by the reference-numeral 9) and a movable part, (designated as a whole by the reference-numeral 10.) The fixed part carries the fixed jaw of the ropegripping device, (indicated at 11,) while the movable member 10 carries the movablcjaw 12. The fixed jaw also carries an alining-pulley 13. The combined hoisting and traction rope 14: is connected at one of its ends to the movable member 10 by means of an arm 15, extending outward from said member at one side of the frame. Said movable member 10 is provided on the other side of the frame with a bearingstud 16, on which is mounted the hoistingrope-guiding pulley 17. It will thus be seen thatthe entire weight of the load is supported by the movable member 10. This latter member is composed of two portions swiveled together by means of a vertical pivot-bolt 18. The lower portion of yoke-like form is provided with a transverse pin 19, adapted to be engaged by the tripping-dog 20, pivotally mounted on the fixed member 9, its pivot being indicated at 21. To the dog 20 there is connected, preferably by a rigid connection, the tripping-plate 22, which is arranged in the path of the sling-pulleys, so as to be engaged by these latter when the load is fully lifted. A trip-rope 24, connected to the trippingplate 22 and passing over a guide-pulley 25, permits the carrier to be tripped at any desired point of elevation of the load below its highest point.

The upper part of the movable member 9 (indicated by the reference-numeral 26) is provided with two upwardly-extending arms 27, which pass upward on each side of the track In the construction illus- 1 and are provided at their upper ends with stop projections 28, lying in the path of the stop projections 4 of the knocker when the movable member is elevated. The arms 27 pass between guide-lugs 29 on the frame of the carriage 5, so that they always maintain the same alinement relatively to the carriage and track. The upper portion 26 of the movable member thus constitutes a swiveling head for said movable member, which always remains in proper relative position with respect to the carriage, track, and knocker, while permitting the lower portion or body of the movable member to turn with the frame of the carrier when the latter is reversed, said lower part being suitably guided in said frame. The carriage 5 has mounted on it on each side of the track a lifting-lever 30, pivoted to the carriage between its ends on a transverse pivot 31. One end of each lever 30 is arranged to engage with the corresponding cam inclines 3, by means of which it is adapted to be operated. I prefer to provide the levers 30 with antifriction-rollers 32 at the said ends to cooperate with the cam-tracks 3. Each lever is pivotally connected at its other end to a link 33, the lower end of which is pivoted at 3 1 to the corresponding side of the swiveling head or upper part 26 of the movable member. The connection between lever 30 and link 33 is preferably a loose connection, the pivot 35 passing through a slot 36 in the link, thereby permitting the levers and links to swing past the central line when the direction of the carrier is reversed, at the same time allowing the gripping-jaws sufficient play to adapt themselves to ropes of different diameters, for it will be seen that when a rope of unusually large diameter is employed the downward movement of the jaw 12 is correspondingly limited, and since the downward movement of the links 33 is determined by the downward movementof the jaw 12, while the pivotal axes 31 of the levers 30 are fixed relatively to these variable limits, the slotted connections between the links and levers provide means for compensating for the variations of distance just referred to.

The ends of the sling are connected to slingblocks 37, which latter are mounted on the bight of the rope 14, so that the bundle will assume the position with its longitudinal axis extending in the same direction as the track, since the bight of the rope is in a plane transverse with respect to the track. The parts being in the position shown in the drawings and traction being exerted on the rope 14, the carrier will move forward in the direction of such traction until the projections 28 of the carrier come into contact with that one of the stop projections 4 of the knocker lying on that side of the knocker from which the carrier is to travel to deliver its load. The carrier being thus held stationary, the load is hoisted until the sling-blocks come into contact with the tripping-plate 22 unless said plate is earlier actuated through the tripping-rope 24. When said tripping-plate is moved upward by either of said means the dog 20 disengages itself from the pin 19, and the movable member 10 having the full weight of the load upon it drops and grips the rope 14 between the fixed and movable gripping-jaws. This downward movement brings the stop projections 28 below the projection 3, and the carrier moves off under the traction of the rope M to deliver its load. After the load is discharged the carrier is returned in the usual manner by a return-rope 38, connected to therear of the frame, and when the carrier again reaches the knocker the rollers 32, coming into contact with the cam inclines 3, will, through the levers 30 and links 33, lift the movable mem her into' the position shown in the drawings, at the same time permitting the dog 20 to engage again with the pin 19 and hold the movable member in lifted position. At the same time the gripping-jaws are opened by the upward movement of the movable member and the sling-blocks and rope are free to descend into position to be connected to the next load. The construction is such that ample leverage is given to effect the lifting of the movable member with a minimum of resistance to the travel of the carrier. When'the direction of travel of the carrier is reversed, the levers 30 are free to swing upon their pivots, so as to lie in a direction opposite to that shown in the drawings, so that the inclination of said levers always conforms to the inclination of the cam inclines with which they are cooperating. The frame of the carrier may thus be readily reversed with respect to the supporting-carriage, so as to travel out in either direction from the knocker without requiring any manipulation of its parts other than the mere turning around of the frame, so as to cause the gripping-jaws of the rope-lock to extend in the opposite direction.

In my prior applications hereinbefore specified the gripping-jaws are shown as arranged at right angles to a line connecting the two points of support of the hoisting-rope on the carriage-frameto wit, the point of attachment of the end of said rope and the rear face of the pulley. This necessitates a setting over of the alining-pulley to a considerable extent and a slight turning of the frame and bundle from the desired position when the load is under traction. To overcome this objection, l have devised the arrangement of these parts shown more particularly in Fig. 5, in which it will be seen that the grippingjaws are arranged at a slight inclination to the line of travel, while the hoisting-rope pulley-has its bearing-stud inclined at a similar angle to the central transverse plane of the carrier-frame, thus bringing the plane of rotation of the hoisting-rope pulley into line ried with its longitudinal axis in accurate alinement with the track.

It is obvious that various modifications in the details of construction may be made Without departing from the principle of my invention. For instance, although the movable member of the frame has been illustrated and described as designed to operate in connection with a rope-lock of the character set forth in my prior applications hereinbefore specified it is obvious that the said movable member and the mechanism for imparting vertical movement thereto may be used in connection with other devices for the purpose. Furthermore, the invention is equally applicable to what is known as a triple-hoist carrier, as illustrated in my prior application, Serial No. 202,005. Although I have shown and described the cam inclines, levers, and links as arranged in duplicate on each side of the track, such duplication is not essential, although preferred, and, again, although I prefer to mount the antifriction-rollers on the levers 30, employing fixed cam inclines on the knocker to cooperate with said levers, it is obvious that this arrangement may be reversed, the roller or rollers being mounted on the knocker, and such a construction is shown in Fig. 6, in which two rollers-38 are employed on each side of the track, respectively, located near the ends of the knocker, while the levers, one of which is shown at 39, are without rollers and engage directly with the rollers on the knocker.

Various other modifications will readily suggest themselves to those skilled in the art, and I therefore do not wish to be understood as limiting myself to the precise details hereinbefore described, and shown in the accompanying drawings.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
